Urea is one of the nitrogen sources for plants to grow. Upon its application to soil, mineralisation takes place, where urea [(NH2)2CO] is hydrolysed and converted to an intermediate compound known as ammonium carbonate [(NH4)2CO3]. Subsequently, it is converted to ammonium ions (NH4+) by urease act...
